used to invert or reverse the
logical state of its operand. Chapter Five: Object oriented programming with Java
When a condition is true,

applying the logical NOT
operator will result in the
condition becoming false

Operator Description Example

= Assigns the value on the right to the int a = 5;
variable on the left.

+= Adds the value on the right to the variable a += 3; // a = a + 3
on the left and assigns the result to the
variable on the left.
-= Subtracts the value on the right from the a -= 2; // a = a - 2
variable on the left and assigns the result
to the variable on the left.

*= Multiplies the variable on the left by the a *= 4; // a = a * 4
value on the right and assigns the result to
the variable on the left.

/= Divides the variable on the left by the a /= 2; // a = a / 2
value on the right and assigns the result to
the variable on the left.

%= Calculates the remainder of the division of a %= 3; // a = a % 3
the variable on the left by the value on the
right and assigns the result to the variable
on the left.

&= Performs a bitwise AND operation on the a &= 1; // a = a & 1
variable on the left and the value on the
right and assigns the result to the variable
on the left.
